First off: Where did you get that tidbit. I don't think it's accurate. It says nothing about it in the man page for ntp.conf, and it works fine on previous version of ntpd. Secondly, and more important, it doesn't help anyway. * If I remove all the "prefer" and try to start ntpd, it still coredumps. * If I set only one "prefer", it still coredumps. * If I comment out the first two servers, but set the remaining two _both_ to "prefer", it runs fine. Thirdly, even if it were illegal to have multiple "prefer" directives, the program still should not coredump because of an invalid config file. So, we come badk to my original statement: After additional testing, it still seems as if the first two servers on this list are coredumping ntpd. -- Bill Moran Potential Technologies http://www.potentialtech.com
